I have 2 eclipse environments on my pc (they operate in a seperate workspace):
* one with the beta where I installed 2.3.0.beta1
* one with the release where I used 2.2.6 sdk
As 2.3.1 SDK was released I updated my "release" eclipse environment (the one where I had 2.2.6), it pulled in the 2.3.1 succesfully through the SDK manager but this action did not update the plugin which in this case of course meant that the Run No Evil target was not available.
After pulling in the plugin in manually through Help -> Install New Software (searching for all versions and picking the right one)... the run no evil target of course becomes available but I don't see everyone do that.
Preferably when fetching a release through the SDK manager it should pull in not only the requested connect iq version but also the plugin that accompanies that release.
